Depends on your power goal and type of fuel being used. I'm on the stock fuel system @ 23psi to 6800rpm, and I still have plenty of fuel on tap. 93 octane. I also run water/meth injection.
If you run an E85 fuel blend over 25%, and 450whp, you may need a LPFP upgrade.

I dont know if I will be using E85, but my step up is like yours and will use 95 octane, which I think its like 92 back here.

I think you will definitely need to upgrade the low pressure fuel pump if you are not running meth, which can alleviate the under fueling.
Some cars even struggle top end with stock Turbos at high boost.

If you know what you're doing, sure. If not look for people who post there buckets for sale for $380-400.
